Everything You Need To Know About Digital Audio Signals
It's been tested and the "best" audiophiles can't hear differences between 14bit and 16bit, nor can they hear differences between 44.khz and ANYTHING higher. In some tests they could use12bit sound with 36khz sampling frequency... The differences they hear are inside their head. Thus the description of improved sound is always "air", "brilliance", "organic" etc.. Don't be fooled by their fancy gear, most of it is for nothing. Cables: i am always willing to bet my months salary on doubleblind tests, 10 000€/m against a coat hanger, no audible differences.. It's all about confirmation bias, you think there's a change and suddenly you hear it.
About MP3s vs PCM:
Here we have audible differences. But. Put on high enough energy, ie turn your amp high enough, suddenly double blind studies can't find which is which. But it can be audible, mp3 is lossy format and even 320kbps can be heard. Not with all material, it's about in the limits of human hearing. Some might hear high end loss, if you're in your twenties. Once you hit 40, everything above 17khz is gone, forever. You will never hear 20k again. And to really notice the difference, you need good gear. Your laptop earphone output most likely won't even output anything past 18khz well and it's dynamic range can be represented with 8bit depth.. It can be just horrible. Fix that with usb box, around 80€: you can take that box anywhere on planet to the most "hifiest" guy out there and he can't hear the difference between his 10000€ A/D converter.. In fact, 5€ A/D converter can produce the same output as 3000€ one... That's not why i said buy a external.. It's more to do with RF and other shielding, protection against the noises a computer makes than A/D conversion quality. Note, i'm talking about audible differences, you can find faults with measuring equipment and 95% of the gear price is about "just to be sure".
If you want a good sound, first, treat your room. Dampen it, shape it.. If you spent 10k on stereo and 0 on acoustics, you will not have a good sound no matter what you do. Spend the same amount on acoustics than what you do on you equipment, room makes a lot more differences than gear. Next comes speakers, they are the worst link in the chain by a large margin. Quality costs, still wouldn't go to extremes here either, the changes are again "just to be sure", not always audible.. Then amps, beefy, low noise, A/B. You don't need to spend a huge lot of money but some. Then cables.. Take the 50€ version instead of 300€ or 3000€. Build quality and connectors, durability. Those are the reason to buy more expensive than 5€. Not because of sound quality.. There will always be group of people that will swear they can hear the differences, that's bullcrap. Human ear CAN NOT detect any chances, even meters are having a REALLY hard time getting any changes. You need to either amp up the signal to saturation point, or use frequencies in the Mhz ranges, thousands of times higher than what media needs to get any changes between cheapest crap and high end scams.
Audiophiles can't be convinced they are wrong, they are suffering from the same thing antivax people do: give them facts, they will be even more convinced they are right.
This goes beyond my knowledge level of signals and waveforms, but it was very interesting anyway.
That being said, OK, I'm sold on the concept that ADC and back doesn't screw up the signal. However, I'm pretty sure that real audiophiles could easily listen to several copies of the same recording at different bitrates and frequencies and correctly identify which ones are higher or better quality with excellent accuracy. I bet that is true even for 16bit vs 24bit, or 192kHz vs 320kHz -- stuff that should be "so good it is impossible to tell the difference".
Since some people that train themselves to have an ear for it CAN detect differences (accurately), the differences must actually be there. If they aren't artifacts of ADC issues, then what are they? I'm guessing compression artifacts?
In a visual version of this, I remember watching digital satellite TV around 10-15 years ago. The digital TV signal was fine and clear -- almost certainly better than what you'd get from an analog OTA antenna. BUT, the satellites used (I believe) mpeg compression to reduce channel bandwidth, and that compression created some artifacts that were easy to notice once somebody pointed them out to you. I specifically remember onscreen people getting "jellyface" anytime someone would nod slowly, or make similar periodic motions. I've got a feeling that some of the artifacts that we (or at least those of us that are real hardcore audiophiles) can notice in MP3 audio files are similar to an audio version of that jellyface kind of issue.

Deconstructing Animated GIFs
I hate GIFs with a passion. Two reasons: 8bit color palette and dithering.
It's a disgrace that even after 25 years there is no better standard to replace this filetype.

I've already taken a look in the vast siftverse for some new tunes and found much non-electronical thanks to you.
Oh and I have edited my last post a bunch of times, I hope you are not too confused by that.
This is also one of my favorites: http://soundcloud.com/epikurmusic/kepos

I'll keep an eye out for them then. I know a few have gone through my playlists.

Hey thanks for the link. Though the song didn't exactly hit my taste... hairs? (you know, in the ear) :
I don't like most of the electronica / d'n'b songs with vocals in it. Very often it just doesn't add anything to the experience, IMO. Although this song was quite ambient and "easy listening".
But I'm always looking for a good electronical tune (no matter what subgenre), preferably with all kinds of influences. I would open a big bucket of power points for somebody who can give me a really good electronica - klezmer sound.

Do you like electronica, and particularly d'n'b?
This one's on 9 and I quite liked it:

Perhaps not quite as much as the violin one that you found in Beggar's canyon, but 1000 times more than the death metal one :

The Pixies "Where Is My Mind?" - 8 bit edition
I appreciate all of the kind words. As the artist I feel I needed to address what the point of this work was... Fight Club came out during my Junior year in high school. I had never really heard the Pixies before that point. I fell in love with the song and listened to it several hundreds of times over. I also happen to love chiptune and ran impulse tracker from an old 486 that I had had since the 9th grade. Put two and two together, and this was the result. There is a built in function in DosBox to record the screen (ctrl+alt+f5). During playback in record mode all samples/intruments are reduced to 8-bit. Channel constraints are not present in the strictest of settings for "true" 8bit. Who cares? Deal with it. Again, thanks for the kind words. You can check out my other words at: .

man that was all kinds of awesome. THIS is 8bit retro! I guess if its not showing tits and a dick people don't vote for this stuff.

BTW, the music is from fantomenK, who does a lot of breakfast pop trance 8bit stuff.

there's a big synth/8bit movement, so I'm guessing he's in 2011 already
